ATTACHMENT FOR SHINGLE-CUTTING MACHINES.

Specification of Letters Patent.

Patented Feb. 4., 1919.

Application filed September 26, 1918. Serial No. 255,850.

To all whom it may concern:

Be it known that I, EDWARD A. LEE, a citizen of the United States, residing at Golville, in the county of Stevens and State of Washington, have invented a new and use ful Attachment for Shingle-Cutting Machines, of which the'following is a specification.

This invention relates to an attachment for shingle cutting machines, one of its objects being to move shingles away from the saw of the machine as they are cut, thereby greatly reducing the danger to the operator handling the machine.

A further object is to provide a shingle moving attachment or flipper which will be operated automatically by the carriage.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claim, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention as set forth in the appended claim.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a perspective view of the attachment, a portion of the shingle sawing machine to which it is attached being shown by dotted lines.

Fig. 2 is an elevation of the attachment.

Fig. 3 is a plan view thereof.

Fig. 4 is an elevation of the adjustable tappet.

Fig. 5 is a plan view thereof.

Fig. 6 is a detail view of the arm for attachment to the flipping blade. 7

Referring to the figures by characters of reference, A and B designate the saws of the shingle machine and G designates a portion of the carriage. The attachmentconstituting the present invention is adapted to be mounted on the ordinary shingle machine and includes a bracket 1 having a socket 2 therein and adapted to be fastened to the frame of the machine just below one of the bearing boxes of the main arbor D. Bearing in the socket 2 of this bracket is the lower end of a shaft 3 having, between its ends, a radial arm 4 to which is bolted or otherwise secured a flipping blade 5 located close to one side of the saw A and having a point which extends close to the front portion of the saw, as shown. The upper portion of the shaft is journaled in a bracket fastened to the top of the adjacent bearing of the main arbor of the machine and which bracket has been shown at 6. A crank arm 7 is provided at the upper end of the shaft 3 and has a rod '8 pivotally connected thereto. This rod is slidably mounted in an arm 9 extending radially from a shaft 10 preferably formed of pipe and the lower end of which is -mounted for rotation on a pintle 11 suitably fastened to the rear portion of the frame of the machine. A nut or head 12 is provided at one end of the rod 8 so that it cannot be casually withdrawn from the arm 9 and a spring 13 is mounted on the rod and bears at one end against the arm 9 and, at its other end against a collar 1% on the rod.

A crank arm 15 extends from the upper end of the shaft 10 and toward the path of the carriage G and a spring 16 is fastened at one end to this arm and at its other end to the frame of the machine, thus to hold the arm normally in the path of a tripping strip or tappet 17. This tappet is formed of two lapping strips 18 one of which is slotted to receive bolts, as shown at 19 thus to provide an adjustable connection between the strips. The strip 18, which is not slotted, is secured to the carriage so that the tappet likewise moves with the carriage. The free end of the tappet is adapted to move against the arm 15 when the carriage C reaches one limit of its movement, for the purpose hereinafter set forth.

For the purpose of bracing the shaft 10 a strip 20 is fastened to the inner bearin of the main arbor D of the machine an also to a convenient part of the machine at its other end, the shaft having a bearing on this strip at an intermediate point as shown at 21.

Under ordinary conditions the point of the flipping blade 5 rests close to the front portion of the cutting edge of the saw A. The stock is fed to the machine in the usual manner and the point of the blade enters between the saw and the shingle being formed. As the carriage C, which moves with the stock, reaches the limit of its back ward'movement,,the tappet 17 which moves with the carriage comes against the arm 15,

spring 13 and rod 8.

swings it against the action of its spring 16, and thrusts through arm 9, against This causes arm K to partly rotate the shaft 3 and swing the blade 5 laterally away from the saw A, thereby throwing or flipping the shingle to one side automatically. As the carriage is moved forward to its original position the parts are automatically restored to their normal positions. It will be noted that the various parts are adjustable to produce different degrees of movement of the blade 5 and to adapt the attachment to machines of different sizes. The attachment can be applied easily and its use will prevent in juries such as have occurred heretofore Where the handling of the shingles at the saw has not been automatic.

What is claimed is The combination With a saw and carriage of a shingle machine, of a" blade at one side of the saw and extending close to the saw, a crank arm revoluble with the blade, a shaft, a radial arm thereon, a rod pivotally connected to the crank arm and slidable within said radial arm, a spring uponrthe rod for transmitting thrust from the radial arm to the rod, a crank arm revoluble with the shaft, a spring for holding it normally in one position and means connected to and movable with the carriage for engaging and actuatin the spring held crank arm to swing the blade and flip a finished shingle away from the saw;

In testimony that I claim the foregoing as my own I have hereto afliXed my signature in the presence of tWo Witnesses.
